“Since 2010, quality of service and expertise is why I choose NH3 Plus for every aspect of our refrigeration infrastructure requirements. In that time, Mike and Ruben have been invaluable in keeping our facilities up and running. Their combined knowledge base has more often than not translated directly into money and time saved. They are without any doubt, my personal recommendation.”

“I maintain approx. 350,000 sq feet of refrigerated space at a large grocery chain using ammonia as the primary refrigerant. I’ve retained NH3 Plus as our primary source for all ammonia refrigerant supply parts and contact resources. I have found the service level at NH3 to be best in class in all aspects of this business, e.g., product knowledge, customer service, delivery of parts, cost and availability of older parts and outside service resources. Don and his customer service and parts manager, Mike, have always come through for our team!”
